How to use the GST / VAT Calculator

  1. Enter the amount and the GST/VAT rate (or pick a preset 5%, 18%, 20%, etc.).
  2. Pick a mode: ‘Add tax’ for an exclusive price, or ‘Remove tax’ to back-calculate net from an inclusive price.
  3. Optionally toggle the CGST + SGST split (India intra-state) and set quantity for the full invoice total.
  4. Read net, tax and gross amounts, plus a side-by-side comparison at every common GST/VAT rate.

Add tax vs remove tax — and why getting it wrong costs money

Adding 18% to ₹1,000 gives ₹1,180. Removing 18% from ₹1,180 gives ₹1,000 — they are NOT symmetric. Removing 18% from ₹1,000 actually gives ₹847.46.

Most invoices show tax exclusive (Net + Tax = Gross). Most shop shelf prices in VAT countries (UK, EU, India MRP) show tax inclusive — use ‘remove tax’ to recover the pre-tax amount.

Indian intra-state supplies split GST equally into CGST (centre) and SGST (state). Inter-state supplies use a single IGST. The total tax is the same either way.
